Biologisch-abbaubarer Vliesstoff und Verfahren zu deren Herstellung

摘要

A degradable non-woven fabric obtained from an web formed of lactic acid-base polymer filaments comprising of one or more lactic acid-base polymer selected from a poly (DL-lactic acid) having more than 80 mol% of L-lactic acid units, poly (DL-lactic acid) having more than 80 mol% of D-lactic acid units, L-lactic acid/hydroxycarboxylic acid copolymer having 70 mol% or more of L-lactic acid units, and D-lactic acid/hydroxycarboxylic acid copolymer having 70 mol% or more of D-lactic acid units, and a preparation process of the degradable non-woven fabric which has good dimensional stability and can be degraded and disappeared under natural environment when abandoned, are disclosed.
